What these tools are NOT
A few things to keep in mind:
- Not magic. The script generator suggests common patterns. You still need to test the output before running on production.
- Not a substitute for learning. They’re a way to save time on the 80% of work that’s repetitive. The 20% that’s interesting still requires thinking.
- Not cloud-dependent. All browser tools run client-side. Your password never leaves your machine.
- Not for sale to investors. The site doesn’t have ads, doesn’t track users, doesn’t sell data. Everything stays free because it’s built and supported on evenings and weekends.
